Putting a scope on my R9.I leveled the scope mount and set scope in place (hung a plumb bob) took the cap off the up and down control put a level on the it and leveled it and it is way off from the plumb line. Level checked left and rt. then turned the level end for end to check the level. Now it comes to what one should I believe? Line or Level
Before you even mount your scope rings or one piece mount to your rifle-Center the scope within it's vertical and horizontal range. The mirror method works well for this. Do a search on GTA.Now, set your gun in a gun vice and try and level it. Front to back and side to side. If you have a flat spot on the gun, put your level there. On most HW rifles you can do this on the barrel.Now mount your scope rings. Take off the top half. Now level across the front rings and them the rear. Now level between the rear right and the front right. Now place you scope in the rings and attach the top sections of the shell, lousy. Now slide the scope into the proper postion for your eye relief. Search GTA for head bob. Once you have that, snug just a little the top caps on your scope rings. Now line up the plumb line with the virtical section of yourscope. Now tighen top scope shell down. usually this is close to 15 inch/lbs.Go shoot.... -Y
